I got another (loopy) compile on alpha-dec-osf3 that went through
cleanly, with the following fixes:

On the x86-*-openbsd host:

* ------------------------------------------------------------------------
  ==fptools== gmake all - --no-print-directory -r;
   in /home/dons/unreg/ghc-6.0.1/libraries/base/cbits
  ------------------------------------------------------------------------

                   from ../../../ghc/includes/Rts.h:20,
                   from longlong.c:29:
  ../../../ghc/includes/TailCalls.h:86: invalid register name for `_procedure'

# Fixed by adding to libraries/mk/boilerplate.mk:
      SRC_CC_OPTS+= -DUSE_MINIINTERPRETER


On the alpha target:

# fix: I_ -> int in ghc/rts/RtsUtils.h ghc/includes/PrimOps.h

* Can't locate file for: -lreadline
  collect2: ld returned 1 exit status

# fix: comment out readline in mk/bootstrap.mk


And then everything went though, to the re-configure part of
hc-build, but the ghc-inplace seems to go into an infinite loop
on invocation. It won't produce output even with invalid command
line flags. It just sits and spins for a few minutes, and then I
have to kill it.

The only interesting thing is that it ignores the first ^C, and
requires a second ^C to die.

I'll try a debug build of some kind. Unless someone has some
better idea.
